A proposed before-and-after workflow
Teams pull ad hoc exports or manually record counters without a documented boundary.
Approved read-only sources publish named signals through a governed gateway, buffer during outages, retain quality flags, and map equipment identifiers to business context.
The future state remains a design until it is tested with the people, data, systems, and exceptions in scope.

Data and decisions needed
Access is limited to what the agreed work needs. Client owners approve source authority, operational rules, and acceptance criteria.
| Reference | Input or decision to establish |
|---|---|
| 01 | Approved source protocols and vendor documentation |
| 02 | Network zones and connectivity constraints |
| 03 | Tag meanings, units, frequency, and tolerances |
| 04 | Equipment and work-order identifiers |

Delivery sequence
A bounded sequence protects continuity and makes learning visible before wider rollout.

Govern
How it fits existing systems
Existing systems are mapped by business responsibility, supported interface, data authority, update timing, and failure behavior. The design may integrate, configure, retain, or replace a component; no universal compatibility is assumed.
Govern
When a different approach may be better
When a use case can be met from an existing MES or historian, reuse that governed source instead of adding a new machine-level connection.
